About This Item

OEM Replacement Impeller for the Pentair Challenger High Pressure Pump

The Pentair 355187Z is the OEM replacement impeller for the Challenger High Pressure Pump, sized for the 3/4 HP Full Rated / 1 HP Up-Rated configuration.

The impeller is the rotating component at the heart of your pump's hydraulic assembly. When an impeller wears, chips, or becomes clogged beyond cleaning, flow rate drops and the pump works harder to move the same volume of water. Replacing it with the correct OEM part restores designed flow performance. Match the part number on your existing impeller before ordering — Challenger pumps span multiple HP ratings, each requiring a specific impeller.

Quantity Included 1

Pro Tip

Before ordering, locate the part number stamped or molded on your existing impeller and confirm it matches 355187Z. The Challenger line spans several HP ratings — an impeller from an adjacent HP configuration will not deliver correct flow and may cause motor overload. If the number on your impeller reads 355187 (without the Z suffix), verify against your pump's serial tag or installation manual that 355187Z is the current replacement before purchasing.
